redis 好像服务器已经关闭了连接

我想使用redis sub/pub，但是当我订阅一个频道时，2分钟后，控制台输出异常： 服务器似乎已关闭连接。

redis版本：redis-3.0.3

jedis版本：2.3.0

操作系统：OS X Yosemite 10.10.5

订阅.class

    JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
    jedisPoolConfig.setMaxIdle(10);
    jedisPoolConfig.setMaxWait(4000);
    jedisPoolConfig.setTestOnBorrow(true);
    JedisPool jedisPool = new JedisPool(jedisPoolConfig, "127.0.0.1", 6379);

    final Jedis jedis = jedisPool.getResource();
    System.out.println(jedis.configGet("timeout"));
    System.out.println(jedis.configGet("tcp-keepalive"));
    final JedisPubSub jedisPubSub = new JedisPubSub() {
        @Override
        public void onMessage(String channel, String message) {
            System.out.println("onMessage");
        }

        @Override
        public void onPMessage(String pattern, String channel, String message) {
            System.out.println("onPMessage");
        }

        @Override
        public void onSubscribe(String channel, int subscribedChannels) {
            System.out.println("onSubscribe");
        }

        @Override
        public void onUnsubscribe(String channel, int subscribedChannels) {
            System.out.println("onUnsubscribe");
        }

        @Override
        public void onPUnsubscribe(String pattern, int subscribedChannels) {
            System.out.println("onPUnsubscribe");
        }

        @Override
        public void onPSubscribe(String pattern, int subscribedChannels) {
            System.out.println("onPSubscribe");
        }
    };
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    System.out.println(dateFormat.format(new Date()));
    jedis.subscribe(jedisPubSub, "/atm/test");

发布类

Jedis jedis = new Jedis("127.0.0.1", 6379);
jedis.publish("/atm/test", "lqiaing---hello");

然后2分钟后控制台输出：

[timeout, 0]
[tcp-keepalive, 0]

有人可以帮助我吗？很感谢！

我不是 OSX 用户，但可能是操作系统配置为终止超过 120 秒的 TCP 连接。您是否尝试过将 tcp-keepalive 选项设置为某个值（例如 30 秒）来检查连接是否仍然中断？
